“…For instance, many organizations do not seem to realize the cost-benefit of involving the users, right from the start of the software development process. According to some authors, UCD has cost benefits, while according to others [6], [27] the usability evaluation methods are not cost effective.…”

Abstract. Patient Centered Design (PCD) is a particular type of User CenteredDesign (UCD) where the end-user is a patient that will use an Information and Communications Technology (ICT) solution for healthcare. It focuses on needs, wants and skills of the product's primary user and implies involving end-users in the decision-making and development process of the solution. e-Therapy aims to provide support to therapy sessions through ICT solutions. It has grown in the last years and in the mental health arena is being used for specific therapeutic contexts. It is an especially difficult environment due to specificities of the patients' conditions and where the physical access to patients is restricted and, sometimes, not even possible. Thus, a PCD approach can be accomplished through the health professionals involved, applying some of the most wellknown methods of UCD: interviews, questionnaires, focus groups and participatory design. eSchi is an e-Therapy tool that complements traditional practices for the cognitive rehabilitation and training of schizophrenic patients. It was successfully developed using a PCD approach.

“…This phenomenon has been quite commonly observed in website usability where it has increased web traffic by 60-100 % [20] . In one study, the sales of software jumped by 60 % and many customers cited usability as a key factor in buying the new system [21] . Major issues with interfaces are: Lack of clarity, use of difficult words and insufficient space to write suggestions.…”

Abstract. Usability has been used to design and assess products and websites. This paper takes the concept of usability one step further and proposes a framework to assess suggestion systems. Thus taking the concept of usability one step further and applying it in the area of ideas management through suggestion system. The fundamental premise of the article is that a suggestion system designed, with usability in mind, will improve innovation among employees, and hence increase participation. This framework was then used to assess four suggestion systems in an oil and gas company in the middle-east. These systems were further assessed for employee perception of their usability and participation. After collecting data on these three different aspects conclusions are drawn. Out of the four systems analyzed, the most usable suggestion system had the highest participation rate and the least usable system attracted the fewest suggestions.

“…This is why they find it so difficult to influence developers' activities and attitudes. At the same time, software developers receive only rudimentary training in usability and user-centered approaches to design, despite the fact that between 50% and 80% of all source code is concerned with the user interface [7], [11]. Along similar lines, other authors [18], [15] acknowledge the importance, for all software practitioners, not only of being acquainted with a variety of usability methods, but also of being able to determine which method is best suited for a particular situation in a software project.…”

Abstract. User-centered design is not just about building nice-looking and usable interfaces, and software development is not just about implementing functionality that supports user tasks. This paper aims to build a tighter fit between human-computer interaction and software engineering practices and research by addressing what software and usability engineering practitioners can learn from each other regarding the impact of usability on software development. More specifically we aim to support usability people in helping developers to elicit requirements that can incorporate usability functions into software development. The paper shows what type of impact usability has on software models and suggests how this impact can be dealt with at the requirements elicitation and specification stages of the development cycle.
